.SH NAME
std::experimental::basic_string_view::find \- std::experimental::basic_string_view::find

.SH Synopsis
   constexpr size_type find(basic_string_view v,          \fB(1)\fP (library fundamentals TS)
   size_type pos = 0) const noexcept;
   constexpr size_type find(CharT c, size_type pos = 0)   \fB(2)\fP (library fundamentals TS)
   const noexcept;
   constexpr size_type find(const CharT* s, size_type     \fB(3)\fP (library fundamentals TS)
   pos, size_type count) const;
   constexpr size_type find(const CharT* s, size_type pos \fB(4)\fP (library fundamentals TS)
   = 0) const;

   Finds the first substring equal to the given character sequence.

   1) Finds the first occurence of v in this view, starting at position pos.
   2) Equivalent to find(basic_string_view(&c, 1), pos).
   3) Equivalent to find(basic_string_view(s, count), pos).
   4) Equivalent to find(basic_string_view(s), pos).

.SH Parameters

   v     - view to search for
   pos   - position at which to start the search
   count - length of substring to search for
   s     - pointer to a character string to search for
   ch    - character to search for

.SH Return value

   Position of the first character of the found substring, or npos if no such substring
   is found.

.SH Complexity

   O(size() * v.size()) at worst.
